Loadsharing IP Packets Over More Than Six Parallel Paths Overview

The Loadsharing IP Packets Over More Than Six Parallel Paths feature increases the maximum number of parallel routes that can be installed to the routing table. The maximum number has been increased from six to sixteen for the following commands:

•maximum-paths

•maximum-paths eibgp

•maximum-paths ibgp

The output of the show ip route summary command has been updated to show the number of parallel routes supported by the routing table.

The benefits of this feature include the following:

•More flexible configuration of parallel routes in the routing table.

•Ability to configure multipath loadsharing over more links to allow for the configuration of higher-bandwidth aggregation using lower-speed links.
